Which can modern taxonomy do?

A. Design tables based on physical characteristics

B. Compare the length of DNA among members of a species

C. compare the length of RNA among members of a species

D. distinguish how closely related organisms are

A

Answer: B. Compare the length of DNA among members of a species

With modern taxonomy, both the internal and external structures of an organism can now be studied and this is important in getting information regarding certain organisms related to ecology. Taxonomy has helped to name and group organisms into an organized biological system. A 2% difference in DNA sequence between two organisms is now considered to be enough to classify them as different species. This is what modern taxonomy can do. With this, comparing the difference in length of DNA among different members of a species can help in making nomenclature and classification even more efficient.
